Abstract (en)

There are provided an intraocular lens injection instrument (200) with improved handleability and an ophthalmic surgical system (1) using the intraocular lens injection instrument. The intraocular lens injection instrument (200) is provided with a casing body (250) having a pressure chamber (RM) variable in its volume varied by a moving wall provided movably inside the casing, a first terminal (254) communicated with the pressure chamber (RM) to connect the pressure chamber with an aspiration pump (40) via a tube (7), and a movable member (294) having one end connected with a moving wall (291) and the other end to directly or indirectly push out an intraocular lens (400), the intraocular lens injection instrument (200) being configured such that the moving wall (291) is movable by a negative pressure in the pressure chamber (RM) to be generated by an aspiration force of the aspiration pump (40) to convert the aspiration force of the aspiration pump (40) into a linear movement of the movable member (294).
